operating ratio
运行率；［动作比，作业比］
The ratio of the number of hours of correct machine operation to the total hours of scheduled operation, e.g., on a 168hour week scheduled operation, if 12 hours of preventive maintenance are required and 4.8 hours of unscheduled downtime occurs, then the operating ratio is (168-12-4.8)/168, which is equivalent to a 90 percent operating ratio.
机器正确运行时间与计划运行的总时间之比。例如，在每周计划运行168小时内，如果预防性维 修需要12小时，故障时间4.8小时，则运行率为(168-12-4.8)/168，即运行率等于90%。 |
